Introducing a small device class for USB Power Delivery. The idea with it is that we do not mix any more USB Power Delivery information into the USB Type-C connectors only. This separation will make it possible to register USB Power Delivery devices also from other places, for example from USB Type-C Bridges (see USB Type-C Bridge Specification). The device class will not always deal with only the messages and objects that were negotiated with the partner, but instead messages and objects that can be used in the negotiation. That allows the USB PD devices to be shared and reconfigured. The ports can decide which objects are to be advertised to the partner before the contract is negotiated. It is also possible to allow the user space to make that decision if needed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
